Developed the Lorentz transformations, which form the basis of Einstein's special relativity.

"One cannot escape the feeling that these mathematical formulae have an independent existence and an intelligence of their own, that they are wiser than we are, wiser even than their discoverers, that we get more out of them than was originally put into them."

— from Attributed remark

"It is not impossible that in the future we may have theories which are more general than those we now possess, and which will reduce our present theories to special cases, just as the theory of relativity has reduced the older mechanics to a special case."

— from Lectures on Theoretical Physics, 1920

"The difficulties which we encounter in the theory of electrons are largely due to the fact that we are dealing with phenomena which are on the borderland between the domain of ordinary experience and that of the infinitely small."

— from The Theory of Electrons, 1909
